  • A novel frequency shifted active radar for local position measurement of
           rail borne vehicles for industrial conditions

      Abstract: This paper presents active radar-based position measurement system for rail borne vehicles. Laser systems are more accurate but fail to perform well in the dusty environment and also due to erroneous alignment. Conventional radar systems are rugged but prone to false echoes from various surrounding metallic structures which are always present in the industrial site. This affects radar-based system adversely and the range gets limited to 50 m. To overcome this drawback, an active radar-based system with frequency shift has been designed and developed which is suitable for industrial conditions and is used in positioning requirements of rail borne vehicles. The proposed system measures distance using return time of flight (RTOF) method. The echo signal is an active signal, generated by the slave to measure distance with very high precision and accuracy. The distance between the stations can be accurately determined over a range of 300 metres using this method with the accuracy of ±50 mm.

  • An overview of methods used for outdoor performance characterisation of
           photovoltaic module string up to 10 kWp

      Abstract: Solar photovoltaic (SPV) energy is most promising among renewable energy (RE) sources. Outdoor performance characterisation of SPV module string using on-field test equipment with a minimum error by reducing the effect of an uncertain operating condition (OPC) is challenging. Improving PV system reliability, flexibility and reducing operation and maintenance (O&M) cost have become a significant factor in increasing the competitiveness of the PV energy market. An illustrative embodiment of literature described herein is particularly suited to select load for current-voltage curve tracer (IVCT) for varying complexities from SPV cell (few Watts) to SPV module string (up to 10 kWp).
      Keywords: current-voltage characteristics; power-voltage characteristics; I-V curve tracer; PV string measurement; performance monitoring; photovoltaic module string

  • Real time measurement of acidity and conductivity in rainwater

      Abstract: To monitor the acidity of rainwater, an automated rain sampler which can measure the real-time pH level and conductivity of rainwater was developed and utilised during the southwest monsoon season. The rainwater sampler detects the start of a rain and collects 250 ml of rainwater. The pH level and the conductivity of the collected rainwater samples were measured and recorded with the prevailing weather parameters. The pH probe was subjected to a verification test using a standard buffer solution whereas the conductivity probe reading was verified using distilled water. The pH level and conductivity measurements including weather data were transmitted to a central location using a GSM modem for further analysis. A programmable logic controller was used to control the entire process. Using the instrument, field measurements were carried out in Kandy in the hill country of Sri Lanka during the months from May to mid September. We conclude from the analysis that there are no changes in the acidity of the rainwater during the southwest monsoon season and the developed instrument can be used successfully for the purpose of environment monitoring in real time.

  • Design and development of dry microneedles electrode-based portable
           wireless instrumentation system for EEG acquisition

      Abstract: A polymer dry microneedles electrode (DME) based portable multi-channel wireless electroencephalogram (EEG) acquisition system was developed in this work. The DME and its electronics were developed as an alternative acquisition methodology to the conventional wet electrode method, which requires skin preparation and application of gels to reduce the skin-electrode contact impedance. In order to overcome the aforesaid issues, dry microneedles electrodes were micromachined of size with base diameter 120 µm, tip diameter ranging between 5-10 µm and height 180-200 µm using biocompatible polymer, polymethyl methacrylate (PMMA) pellet and coated with metallic and metal nitride films to a total deposited film thickness ranging between 800-850 nm, those were both biocompatible and conductive. The proposed instrumentation system includes an EEG sensing circuitry comprising filters, amplifiers, an analogue processing unit, a digital signal processing circuit comprising microcontroller and a Bluetooth wireless transmission module for loss-free signal transmission preventing signal distortion and cable noise. The developed electrodes were characterised for their electrical properties to acquire EEG signals from the frontal lobe of the brain. The performance of the developed electrodes was evaluated with respect to conventional wet electrodes using developed wireless instrumentation system and found that the amplitude and frequency response of both electrode systems had an average correlation and coherence of more than 90% proving that DME could be a futuristic alternative to conventional EEG acquisition systems.

  • Machine vision-based hot strip speed measurement system

      Abstract: Minimisation of crop loss has been a great concern to the steel makers since the inception of hot strip rolling process. It has been observed that the loss of steel due to essential cropping of transfer bar at hot strip mill is significantly high, in the absence of a reliable strip speed feedback to crop shear, which crops the irregular ends of hot strips. Therefore, an innovative transfer bar speed measuring system has been developed in-house based on the principle of machine vision. On successful implementation of this system, average yield loss due to crop-cut has been brought down, and thus, improvement of gross yield of HSM resulted in substantial recurring savings.
